' To all whom may concern:

bined pliers and wrench, thedevice being equipped with novel. means formaking adustment in the size of the jaw opening for facilitatinengagement upon articles or objects oi diherent sizes. 1

An important object is the provision of a tool of this character whichwill be simple and inexpensive in manufacture, highly eficient in use,easy to adjust, durable and practical in service, and a generalimprovement in the art, With the above and other objects and advantagesin view the invention consists in the details of construction to behereinafter more fully described and claimed and illustrated in theaccompanying drawings, in which:

Figure 1 is an elevation of the showing it in closed position,

Figure Q is a similar View showing it in open position,

Figure 3 is a similar view with various parts in section to illustratethe connection and showin the adjustment feature for re%ulating the sizeof the jaw opening,

igure 4t is a detail cross section on the device line ll of Figure 1,

Figure 5 is a detail cross section on the line 5-5 of Figure 1,

Figure 6 is an edge elevation.

Referring more particularly to the drawings the numeral 10' designates arelatively stationary handle which terminates at one end in. a curvedrelatively fined jaw 11 which has its active face curved and formed withteeth 12. The other end of the handle 10 termniates in a reducedthreaded ertension 13 upon which is screwed a nut 1d for a purpose to bedescribed The numeral 15 represents the relatively movable jaw whichco-operates with the jaw 11 and which likewise has its inner acepreferably. curved and toothed as indicated at 16. This java member 15is bifurcated to define arms 17 which straddle the handle member 10 andwhich are pivoted therer the operator out that the jaw 15 will be to asshown at 18 by means of a bolt, rivet, pin or the like;

The relatively movable handle is designated by the numeral 19 and hasone end tltting within the bifurcation in the jaw menaber 15 and pivotedby a pin, or rivet 20. ()n the intermediate portion of this handle 19 isa projection or lug 21 which is adapted to engage against the handlemember 16 intermediate the ends thereof whereby to form a stop. Thenumeral 22 represents a link which has one end "torked and straddlingthe lug 21, pivotal connection being efi'ected by means of a pin orrivet 23. The other end of this link has its lace toward the handle 10concaved as indicated at 2% and pivotally carried by the extremity is asmall yolre 25 which embraces the threaded extension 13 for adjustmentpurposes to be described a v While it is not obviously essential weprefor to employ a spring 26 which is of the leaf type and which isriveted or otherwise secured onto the member 10 as shown at 27, its freeend bearing against the relatively movable handle lt for the purpose ofurging it normally in one direction so that when the device is used aspliers it will automatically adjust itself.

The open position of the tool is shown in Figure 2 and it willbeqohserved that in this position "the jaws are open and the handle 19is away from the handle 10. To use the device as pliers, the jaws 11 andare engaged upon thearticle or objects while holds the handles 10 and 19within one hand. When the handles are subsequently squeezed together, itis appar swung upon its relation with the ivot 18 into clampin eClllVGgrip may be aw 11 so that an e had upon whatever is to be turned. sizeof the opening of the jaws is regulated by the position of the nut isupon the threaded extension 13 as is clearly shown, it being notablethat the yoke 25 may be engaged between any two selected threads formaintaining the adjustment. For oi:- ample when the nut l l is run outto near the end of the threaded extension and the yoke 25 engages theextension near the nut, the device is capable of engaging articles oflarger size then when the reverse is true and the jaws 11 and 15 willnot come together even though the handle 19 bepressed to its maximumdegree toward the handle The said fixed jaw and 10. For gripping smallarticles, the yoke 25 must be located nearer the juncture of theextension 13 with the end of the handle and the nut 14 must be run up orin on theextension.

When us ng the device as a wrench, it is 0t necessary to move the handle19, the ad-' justment of the size of the opening between the jaws beingregulated merely by turning the nut 15. In this instance, as the nutbears against the end of the link 22 the handle 19 and jaw carriedthereby will be moved to effect the adjustment.

From the foregoing description and a study of the drawings it-will beapparent that we have thus provided a simply constructed andconsequently inexpensive tool which will be highly etficient for thepurpose specified and plicity is not likely to get out of order so thata long life should be assured.

ile we have shown and described the preferred embodiment of theinvention it is of course to be understood that we reserve the right tomake such changes in the form, construction and. arrangement of parts aswill not depart from the spirit of the invention-or the scope of thesubjoined claims.

Having thus described our invention we claim:

' 1. A'tool of the character described comprising a relativelystationary handle terminating at one end in a fixed jaw, a curvedrelatively movable jaw co-operating with terminating in arms and pivotedupon said handle straddlin first named jaw, a relatively movnear theable handle pivotally connected with the inportion of said movable jaw,a link pivotally connected at one end with the termediate intermediateable handle, able on the j which the other end of said link engages.

2. A tool of the'character described comportion of, the relativelymovand an abutment member mov- .prising a relatively stationary handletermi which on account of its Sinkfirst named handle and against at oneend in a fixed jaw, a curved movable jaw co-operating with said fixedjaw and terminating in arms straddling and pivoted upon said, handlenear the first named jaw, a relatively movable handle pivotallyconnected with the intermediate portion of said movable jaw, a linkpivotally connected at one end with the intermediate portion of therelatively movable handle, and an abutment member movable on the firstnamed handle and against which the other end of said link engages, saidrelatively movable handle being formed intermediate its ends on its facetoward the first named handle with a lug engageable therewith whereby tolimit the movement.

3. A tool of the character described comprising an elongated relativelystationary handle terminating at one end in a fixed jaw and having itsother end formed with a reduced threaded extension carrying a nut, arelativel movable jaw of bifurcated formation stra dling and pivotedupon said relatively stationary handle near the fixed jaw thereon, anelongated relatively movable handle pivoted within the bifurcation ofthe relatively movable jaw at the intermediate portion thereof, aleaf'spring carried by the relatively'stationary handle extending withinthe bifurcation of the movable jaw and engaging the pivoted end of saidrelatively movable handle, the intermediate portion of the relativelymovable handle being formed with a lateral extension projecting towardthe relatively stationary handle to serve as a stop, a yoke straddlingand pivoted upon said extension and having a heel adapted to engage uponsaid nut, and a loop carried by the free end of the yoke adjacent theheel and embracingly engaged about said threaded end.

In testimony tures.
